Question 297402: Find two consecutive integers such that the square of the sum of the two integers is 11 more than the lesser integer.
I'm having a terrible time solving this. According to the book, the answer should be (-2,-1).I believe the formula is:
x = lesser #
x+1 = greater #
(x+x+1)^2=x+11
(2x+1)^2=x+11
4x^2+4x+2=x+11 (subtract the x+11 to bring it to the other side)
4x^2+3x-9=0 (this is also where I get stuck)
